CHANGE SOUGHT: European regulators have asked Google to clarify its new privacy policy and make it easier for users to opt out of it.

THE CONCERNS: Regulators worry that Google may be collecting too much data and holding the information for too long. The concerns stem from Google's new unified privacy policy, which replaces individual policies for search, email and other services. The policy allows Google to combine data collected from one person using its disparate services.

RESPONSE: Google says it's reviewing the EU report but believes its policy respects European law.
